IMPROVEMENT IN RuluNlIxlc-z-GE/msl FOR VEHICLES.

Specification forming part of Letters Patent No. 148,497, dated Marchl0, 1874; application filed December 3l, 1873.

To all whom it may concern." f

Be it known that I, GYRUs W. ALADEE, of Pittsburg, in the State ofPennsylvania, have invented certain new Improvements in Gearing forVehicles, of which the following is a speciiication:

Thev iirst part of my invention consists in bending the front and rearholsters and side perches in one piece, and splicing them together at orabout the cross-center of the gearing, in such manner as to make,literally, an endless perch for carriage-gearing.

The second part of my invention consists in supporting and operating twohalf-elliptic side springs between the two outside perches and upon twoseparate connecting-rods, the hearings of which latter are also securedto the perches.

Carriage-gearing with two or more perches have a bolster resting uponboth the front and rear axles, and in or upon which is secured theopposite ends of the two outside perches, each corner of the gearingpresenting two ends, viz., the end of the perch and the end of theholster, to be finished with a scroll, or otherwise, besides involvingthe cost of bolts and other necessary fastenings to make theseconnections secure. To obviate all this, I proceed to unite the holstersand side perches as follows, viz: In the first place, I take two piecesof wood of the required thickness and depth for the holsters at theirheaviest point, and of a length equal to the length of one bolster andthe half-length of each perch. These pieces are now bent intosubstantially the form shown from H to F of the drawing, and with theround corners S S S S. The opposite ends of these pieces A and Al arethen finished up as required, and are spliced together at F and F, afterwhich the side perches A and A are plated with iron, in the usual way.It will now be seen that Ihave produced an endless perch by bending theholsters A with the side perches A, and splicing the latter at or aboutthe erosscenter of the gearing. By this means, I not only get rid ofjoining the perches A to the ends of the holsters A at S, and the workof inishing the ends of each, as

lis required upon the old plan, but produce a cleaner and smoother inishat these points, and save a great deal of work in the iron connections,otherwise necessary at these points. In-all cases where elliptic springsare to he used over the front and rear axles, they are made to rest uponthe ends of the perches or holsters A', between the dotted lines E, butin this case the front holster A will he made considerably shorter thanthe hind one, so that the rear ends of the perches A will be fartherapart than the front ends, and not parallel to each other, as seen inthe drawing. If prcferred to bend the perches in one piece, only onesplice, F, will he necessary.

I am aware that two perches have been bent in one piece, as shown anddescribed in the patent of John Gurtice, of Cincinnati, Ohio, and in aformer patent of my own. In the former case the perches are closed bythe bend in front of the head-block over the front aXle, with the rearends of the perches left open and framed into the hind axle-bed orholster, while in the latter case the perches are closed by the bend inthe rear of the hind aXle, and the front ends left open and framed intothe head-block over the front axle. But my present invention, let it bewell understood, differs materially from both of the forms abovedescribed, as well as from all other kinds of bent perches of which Ihave any knowledge, in this, that both ends of the perches are closed bythe bend of the woodmaking the holsters and perches, when completed, inone continuous piece, or, in other terms, an endless perch.

The halfelliptic side springs B and B are linked to two separateconnecting-rods, C and C, at D, between the two opposite perches A andA, and the body of the vehicle is then supported upon the center of thesprings, in the usual way. rBhe bearings in which the connecting-rodsare hung and operate are also secured to the perches, and not to thebolsters, as is the general custom.

Two advantages are attained in this mode of suspending the springs uponand between the perches, viz., first, the springs being suspended zuidoperating between the perclies,`

instead of 011 the one side of them, :is is usual, the body can neverstri kc the perclies by the over-depression of -the springs; and,second, the perches being on theoutside of the springs, I can attach thesteps directly to the perche-s, und not to the springs, as is usual, bywhich I gain the advantage ot relieving,` the springs of the strainimposed upon them in all cases Where the steps ure secured to either thebody or springs, us is 110W the almost universal custom.

I claim as my invention- 1. An endless perch, A and A', substantially asand for the purpose set forth.

2. Connectingods C and C, pivoted at or near the opposite ends of theperehes Aand A, and provided with links D and springs B and B, allcombined to operate between the opposite perches A and A, substantiallyas und for the purpose set forth.
